Hot dogs originated in Germany. In Germany, hot dogs are called sausages, which originated in the German city of Frankfurt. This kind of sausage was later spread to America, and Americans called it "sausage".

In the United States, vendors selling sausages will carry a hot water tank on their chests, which contains insulated sausages and sell sausages. People often eat this kind of sausage with bread between them.

1906 A cartoonist drew this kind of sausage he saw and published it in the newspaper. However, he drew a loaf of bread with a sausage in it instead of a sausage. Because he can't spell the word "sausage", he wrote the word "hot dog" under the cartoon. Since then, the name hot dog has been used by people.
